Contact Nautilus 800-331-3578, if you haven't already. That screw at the top was breaking regularly and was a common problem. Unless they are no longer producing this part, they should still have it or be able to point you in the right direction. I see that fitness repair parts no longer has them which surprises me. If you still come up empty then let me know and I will do my best to dig a little deeper. Hope you find it. If you do, make sure you add lubrication to that screw, which is nautilus' solution to a bad design.
